Well its 2.30am, been asleep since 10pm and awake since 1am. Yet another symton of Hashimot0's or too much Thyroxine? Did have an increase in thyroxine last week from 100 mcg to 125 mcg - have to say that I,ve had sleep problems since being diagnosed 7 months ago, but not as bad as this. Assume I will have to persevere and let things settle? Are there any more night owls out there?
